The young Otto is played by Truman Hanks, Tom's son, who was 26 years old during principal photography.
In the cars scene with Otto and Reuben, Tom Hanks' face was digitally de-aged to make him appear in his mid thirties. The VFX team used footage and stills from The 'Burbs (1989) to create a digital blueprint in order to achieve this effect.
The original Swedish film adaptation was nominated for two Academy Awards and was the highest grossing foreign film of 2016 in the United States.
Rita Wilson (Tom Hanks' wife) contributed to the movie soundtrack. She sang "Til You're Home" with Sebastian Yatra.
When Otto approaches the BMW playing rap, the song being played is "White Boy Summer" by Tom Hanks' son Chet Hanks.
